Mountain Weather brief

Northwest Highlands

Monday 19 October 2026 · Wester Ross, Assynt and the far northwest

Confidence: Medium Why?

Uncertainty over high-ground wind strength. Uncertainty over sky cloud cover and sunshine.

What matters most

A good day in the Northwest Highlands, though expect a blustery wind.

Conservative regional grades across representative summits, so one sheltered hill does not overstate the wider area.

01

High-ground wind (900 m)

At around 900 m, expect a southerly wind of 20–30 mph, gusting 30–40 mph. Gusts like that are strong enough to make walking into it hard work, with buffeting on ridges and edges.

02

Walking impact

Gusts of 30–40 mph are strong enough to make walking into it hard work, with buffeting on ridges and edges.

03

Rain and showers

It should stay dry.

04

Cloud-free summits

Clear-summit estimate: about 90% early, about 90% around midday and about 80% later.

05

Cloud and visibility

The tops should stay mostly clear of cloud. Good spells of sunshine are likely. The air should be clear, so expect far-reaching views as long as the tops stay clear.

06

Temperature and wind chill

At around 900 m it will be 2 to 6°C, feeling like -4 to 0°C in the wind. Take a hat, gloves, a windproof and a spare warm layer.

07

Freezing level

The freezing level is close to summit height.

08

Daylight

Sunrise 08:02, Sunset 18:06, about 10.1 hours daylight.

Full regional overnight outlook

Too windy for an exposed pitch up around 900 m on some hills. Lower down, a mixed night to camp, mainly because of the wind. Gusts reach about 40 mph around 900 m and nearer 30 mph around 300 m, which makes for a noisy, testing night even in a good tent. Check the forecast for the hill and height you have in mind, and don't assume lower ground will be sheltered. It should stay dry. Overnight lows of about 3°C at 900 m.

Regional climbing & scrambling outlook

A broad guide to dampness and exposed rock across the area, not a forecast for every crag. Lower, sheltered crags and individual rock types may behave differently.

Conditions for exposed scrambling across the area look fair (73/100). Rock is likely to be mostly dry, though local seepage and shaded holds remain unresolved. Gusts may reach about 35 mph on exposed ground, making crosswinds an important route consideration. Mapped summit-point geology across the representative hills includes psammite, pelite or semipelite and sandstone or gritstone. Rock can therefore respond differently to moisture between crags and routes.

Damp sandstone and gritstone can feel greasy, and saturated sandstone may be weakened, so let the rock dry fully.

Recommended kit for this dayWeather-aware packing prompts, plus your core hillwalking kitView kit

For a day hillwalk, not a complete route-specific checklist. Carry navigation and backup you can use, warm and waterproof layers, suitable footwear, food and water, a headtorch, emergency shelter, first aid and a way to call for help. Snow, ice, technical terrain and overnight trips need additional equipment and skills.
